Below, describe the present invention with reference to the accompanying drawings.
Fig. 1 illustrates built-in antenna according to an embodiment of the invention, and (a) of Fig. 1 is stereogram, and (b) of Fig. 1 is stereogram lower surface being placed in top, and (c) of Fig. 1 illustrates the state launching polymer film.In FIG, shorter direction represents Width, and longer direction represents length direction, and is suitable for too in embodiment afterwards.
Built-in antenna 100 is made up of following key element: the core (core) 110 of 3D shape; Adhesive phase 120, the coated core of broad ways and bonding; Polymer film 130, is adhered to adhesive phase 120 with coating and bonding oxidant layer 120; And antenna element 140, be formed on polymer film 130.
Here, consider situation built-in antenna 100 being electrically connected to circuit board by Reflow Soldering, core 110 and adhesive phase 120 and polymer film 130 can have the thermal endurance can bearing welding.
Antenna element 140 is made up of metal material, and eliminated into by chemical etching or laser the pattern determined, thus forming antenna pattern unit 142 and electrical connecting unit 144,146, the electrical connecting unit 144 being electrically connected to antenna pattern unit 142 can be separated by the lower surface of core 110 with another electrical connecting unit 146 not being electrically connected to antenna pattern unit 142 and be formed.
< core 110>
Be positioned at the 3D shape that inner most core 110 provides built-in antenna 100, and owing to being formed to have flexible polymeric material, therefore easily bent by the operation of operating personnel.
As required, the electro-magnetic wave absorption powder of electromagnetic wave absorption can make the electromagnetic core 110 of Absorbable rod by adding at core 110, thus the characteristic of built-in antenna 100 can be improved.
Core 110 can use has pliability and inelastic polyimides (polyimide:PI) resin or have flexible silicon rubber, section shape can be not only the rectangular shape that two ends are as shown in Figure 1 protruded downwards a little, but also can be highly low sheet or the tubulose being formed with through hole along its length.
In section shape as shown in Figure 1, corner, both sides, top respectively with rounded shapes formed, thus with mutual towards object carry out can preventing from the process of assembling two sides are stuck.
When the section shape of core 110 is tubulose, the section shape of through hole can diversely be formed, and can be dumbbell shape (or peanut-shaped), circular or oval or trapezoidal, and when circular or oval can be formed in pairs.
< adhesive phase 120>
Adhesive phase 120 is between core 110 and polymer film 130, thus reliably bonding core 110 and polymer film 130.
When needs pliability and elasticity, adhesive phase 120 can solidify liquid silicon rubber and be formed.
In addition, when considering the connection by means of welding, adhesive phase 120 can be melting and maintain the resinoid of bonding force again under the effect of heat owing to can not apply when welding.
The same with core 110, as required, the electro-magnetic wave absorption powder of electromagnetic wave absorption can make the electromagnetic adhesive phase 120 of Absorbable rod by adding in adhesive, thus the characteristic of antenna can be improved.
In addition, the average thickness of adhesive phase 120 can be 10 μm to 100 μm.
< polymer film 130>
As mentioned above, polymer film 130 can be have flexible polyimide film, and the thickness of polymer film 130 can be approximately 5 μm to 50 μm.
As mentioned above, the face of polymer film 130 being adhered to adhesive phase 120 can form electromagnetic wave absorbing layer as required.Such as, by by the coating of the electromagnetic wave absorb of liquid state or be printed in polymer film 130 correlation surface after form electromagnetic wave absorbing layer by solidification.
< antenna element 140>
As shown in (c) of Fig. 1, antenna element 140 is made up of following key element: a pair electrical connecting unit 144,146, is formed in mode electrically separated each other at the two ends of Width; And antenna pattern unit 142, be electrically connected with an electric connection terminal 144 in electrical connecting unit 144,146, and extend to another electric connection terminal 146, thus there is antenna performance.
Antenna element 140 is formed at the face externally exposed of polymer film 130, such as, at the polyimides of the metal forming direct casting liquid making state of formation antenna element 140, and form polymer film 130 by solidification, thus antenna element 140 finally can be made to be adhered to polymer film 130 and to be formed.
Unlike this, the antenna element 140 of polymer film 130 and metal material is bonded to each other by sandwiched heat-resistant adhesive.
Especially, this structure be made up of polymer film 130 and metal forming is known technology as flexible copper foil base material (FCCL:Flexible Copper Clad Laminate).
Antenna element 140 can use elongation excellent and can carry out the Copper Foil of such as 6 μm to about 30 μm that weld.Copper Foil can there be gold, tin or silver to prevent corrosion by plating.Like this, by using Copper Foil, even if be repeatedly extruded, crackle (crack) can also be prevented.
Due to by metal sputtering in polymer film or with compared with the situation of metal deposition, when using Copper Foil, conductivity is low, and therefore antenna performance improves.Especially, when the width of antenna pattern unit 142 is narrow, Copper Foil is more effective.
As described below, the electrical connecting unit 144 being electrically connected to antenna pattern unit 142 is electrically connected with the conductive pattern of circuit board, is not electrically connected to the electrical connecting unit 146 of antenna pattern unit 142 and is electrically connected with other conductive patterns of circuit board or dummy pattern (dummy pattern).
With reference to (a) of Fig. 1, electrical connecting unit 144,146 is separated by the lower surface both sides of built-in antenna 100 and is formed, and crosses over the whole length direction of built-in antenna 100 respectively and formed.In other words, be formed as all covering along its length and by the part of being separated by of the lower surface of built-in antenna 100, its result can reduce the contact resistance between the conductive pattern of circuit board.
In this embodiment, although enumerated electrical connecting unit 146 example electrically separated with antenna pattern unit 142, can be electrically connected according to required antenna performance or purposes.That is, a pair electrical connecting unit 144,146 is electrically connected to antenna pattern unit 142.
Antenna pattern unit 142 between electrical connecting unit 144,146 is etched by the part of the antenna element 140 of metal material or is removed by laser and formed, and extend from the electrical connecting unit 144 of electrical connection to other electrical connecting unit 146, thus cross over the two sides of actual built-in antenna 100 and upper surface and formed, thus there is 3D shape.
In one embodiment, antenna pattern unit 142 has complications (zigzag) shape repeatedly along its length, but is not limited thereto, and can carry out the shape of diversely designing antenna pattern unit 142 according to the performance of required built-in antenna 100.Such as, the antenna pattern unit 142 of paster antenna (patch antenna), helical antenna (spiral antenna) etc. can be formed as.
In addition, antenna pattern unit 142 is electrically connected to the conductive pattern of circuit board by electrical connecting unit 144.
In addition, antenna pattern unit 142 by covering the impact protecting antenna pattern unit 142 not to be subject to from external environment condition or impact with insulating material, thus prevents antenna performance from changing.
As an example, antenna pattern unit 142 can apply photosensitive insulating resin (PSR) and so on polymer or can bonding polymer film, thus can insulation protection antenna pattern unit 142.
In the case, a part for antenna pattern unit 142 is made as above not form insulating material on the surface, to make relevant portion can from external electrical connections, or for being easy to adjust the performance of built-in antenna 100 after making manufacture built-in antenna 100.
